Preliminary Study on Nanometer Grouting Materials

The application of grouting technology in the reinforcement and water shutoff of underground engineering is very extensive. The grouting technology mainly includes two aspects: grouting process and grouting material. The grouting material is a vital link in grouting. It affects the cost of construction directly, and determines the success or failure of the engineering. The smaller the molecular dimension of solution or solid particle dimension, the greater the scope that the grout can be injected into. And it is beneficial to the grouting effect. With the development of nanotechnology, the development of nanometer grouting materials is feasible, and is also a great breakthrough for the grouting technique.
